Good morning,

I currently have a single node server with 8TB of raid 5 available to it internally. Within my vmdata Volume Group I have two thinpools. Plexmedia and vmstore, vmstore is holding onto an old VM (vm-103-disk-0) that I was using and will not delete. It is holding up 2 TB worth of space and I would love help trying to get rid of it.

Thank you,

-B.

Assuming that you have a backup of all your data, you could look into the following to fix the metadata:

Code: 
lvconvert --repair vmdata/vmstore

Here is my output:

Thanks. And just for the sake of documenting it here (should that link ever go offline):

Code: 
vgcfgbackup -f  vg.bak   vgname

edit vg.bak and remove all thinp related volumes

Code: 
vgcfgrestore -f vg.bak  vgname
